My experience with dog owners suggests they are pretty much deaf. At least to their dogs barking.
Record the barking on a loop and play it for them when they are sleeping.
If one night of that don't work, leave it play for a weekend while you are away, or even a week.
Ya gotta make sure it is very loud and annoying.

I like steaks too.
Neighbors dogs used to get into the wifes chickens.
She locked the dogs in the kennel and called them on the 1st offense.
2nd offense I locked one of them in the kennel and ran the 2nd dog home with a .40 cal glock. I made it a point not to shoot the dog, just make a bunch of noise. Then called and told them if they wanted the second dog back they should hurry over as I was getting ready to take it for a ride..
Neighbors arrived, pretty much pissed that I had scared one dog home and locked the other one up.
With Glock in one pocket, and Judge in another, I explained that I did not want to hurt anyones dogs or they would have already been shot. Also mentioned that this was the second time and I hoped there would not be a third. As I would not call them again. Did not mention that I would have called animal control though.
No more problems with the dogs. Or those neighbors.

It's all about the money. If it's illegal it costs more and there is no taxes paid. Here in Oregon is seems the price has gone down to the point that some people are even giving it away.
Still no taxes on that that is given away, but it does not support criminal enterprise.

A couple years are so I was running a 9090DB at 11-1200 on the volume.
Speaker output wires for left channel shorted ( + to - ) and left Khorn quit singing.
Dang, hooked up another receiver and set the db aside.
Sent it in to be restored.
Left speaker worked when it arrived after shipping.
Anyone have any Ideas what may have happened?
Should I have the output transistors replaced just in case?
Any thoughts?
